This Town in Australia Looks Totally Deserted. But Turns Out Their Residents Are Just Brilliant.

The town of Coober Pedy in northern South Australia (wait, it gets even more confusing) is the opal capital of the world. Nearly 95% of the world’s opal supply comes from the local mines. But, if you were to walk into this mining town of 3,000 people, you wouldn’t see a bustling little town. You’d actually see less than half of its population.

That’s because half of the people who live in Coober Pedy live underground.
